"A new page in the history of the principality has opened today," Albert told his subjects in a post-ceremony address. "I know that (Princess Charlene's) spontaneity and generosity will come into full bloom... to the great joy of the principality and its inhabitants."

After the ceremony, the bride and groom mingled with their subjects in the palace square for a cocktail party. After Saturday's second ceremony, the couple will host a star-studded gala reception with a guest list including Karl Lagerfeld and Giorgio Armani -- who reportedly designed Wittstock's gown for Saturday -- as well as Naomi Campbell, Sir Roger Moore and Nadia Comaneci.

Prince Albert, 53, met the 33-year-old Wittstock in 2000 and the couple became engaged a year ago. He has two children out-of-wedlock with two different women and had long been considered a consummate bachelor. He rules over the six square mile principality where his American-born movie star mother, Grace Kelly, became a princess.
